Possible Duplicates:
What does zero-sized array allocation do/mean?
C++ new int[0] — will it allocate memory?

int * p;
p = new int[ 0 ];

What is the expected outcome when new is called for zero number of elements? Is the outcome defined or undefined?

Further, is it okay to call

delete [] p;

on that pointer?

What is the intuition/analogy to this situation of pointer to an array of zero elements?

Thanks in advance. Regards, Arun
